Description

Technical Field

[0001] This invention relates to the field of PCU (PCU) center cover processing technology, and particularly to a die casting material head removal device and method for PCU center covers. Background Technology

[0002] PCU, or Power Control Unit, is a control unit for hybrid and electric vehicles, used to control the motors during startup, acceleration, deceleration, and driving. The PCU cover is typically formed by die casting before being processed into flow channels and slag bags.

[0003] In the existing technology, the slag head removal method for die castings is usually a one-time punching method. However, due to the special connection structure of the slag head of the PCU cover die casting, that is, the special relationship between the position of the slag pot and the runner, the slag pot is connected to one side of the PCU cover die casting, while the runner is connected to the lower part of the other side of the PCU die casting. If the existing one-time punching method is used, the runner cannot be completely removed. Therefore, the existing punching equipment is not suitable for the slag head removal of PCU die castings.

[0004] Since there are no reports in the existing technology of cutting equipment specifically designed for the structural characteristics of PCU middle cover die castings, the removal of the slag from PCU middle covers usually requires manual removal using a handheld electric saw. This method is not only inefficient when mass-producing PCU middle covers, but also makes it difficult to ensure stable and uniform cutting quality. Summary of the Invention

[0005] The technical problem to be solved by this invention is: how to improve the cutting efficiency and cutting quality of the cover head in PCU.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0021] The slide is slidably connected to the guide rail;

[0022] A driving device is used to drive the slide to move along the guide rail;

[0023] A saw blade, wherein the saw blade is rotatably connected to a slide block, and a plurality of the saw blades are arranged in a line along the left-right direction, and the axis of the saw blade is vertical;

[0024] An electric motor is connected to the saw blade drive and is used to drive the saw blade to rotate.

[0025] Furthermore, the die-casting material head removal equipment structure for the PCU cover also includes a cooling component.

The end of the coolant spray pipe is provided with a coolant nozzle, which faces the edge of the saw blade.

[0026] Furthermore, in the aforementioned PCU cover die casting material head cutting equipment structure, a conveyor belt is provided below the positioning seat.

[0027] Furthermore, the die-casting material head removal equipment structure for the PCU cover also includes a mounting plate. The mounting plate is connected to the lower end of the piston rod of the second drive cylinder. The slag bag removal plate is fixed to the mounting plate. The mounting plate is provided with two limiting shafts parallel to the piston rod of the second drive cylinder. The two limiting shafts are symmetrically distributed on both sides of the second drive cylinder. The crossbeam is provided with bushings that slide with the limiting shafts.

[0028] Furthermore, in the above-mentioned PCU cover die casting material head removal equipment structure, the clamping component includes two cylindrical clamping blocks distributed on the left and right.

[0029] Furthermore, in the above-mentioned die-casting material head removal equipment structure for the PCU middle cover, the positioning seat is provided with a positioning post for passing through the through hole of the PCU middle cover.

[0030] Furthermore, in the aforementioned PCU cover die casting material head removal equipment structure, the first drive cylinder is a pneumatic cylinder, hydraulic cylinder, or electric cylinder, and the second drive cylinder is a pneumatic cylinder, hydraulic cylinder, or electric cylinder.

[0031] This invention also protects a cutting method for the die-casting material head cutting device of the above-mentioned PCU cover, comprising the following steps:

[0032] Step 1: Position the die-cast part of the PCU middle cover on the positioning seat, with the inner surface of the PCU middle cover facing upward, so that the slag pocket of the die-cast part of the PCU middle cover is located in the gap between the positioning seat and the support seat.

[0033] Step 2: Control the piston rod of the first drive cylinder to move downward, driving the clamping component to press the die-cast part of the PCU middle cover from above;

[0034] Step 3: Control the piston rod of the second drive cylinder to move downward, driving the slag bag cutting plate to cut the slag bag from top to bottom, and causing the slag bag to fall out from the gap between the positioning seat and the support seat;

[0035] Step 4: Control the piston rod of the second drive cylinder to move upward, which will drive the slag bag removal plate to move upward and detach it from the die-cast part of the PCU cover;

[0036] Step 5: Control the piston rod of the first drive cylinder to move upward, driving the clamping part to move upward and disengage from the die-cast part of the PCU middle cover;

[0037] Step 6: Control the motor to drive each saw blade to rotate, control the drive device to drive the slide to move towards the positioning seat, so that the saw blade contacts the flow channel of the die-cast part of the PCU cover, cuts the flow channel, and falls downward.

[0038] Step 7: Control the drive device to move the slide away from the positioning seat, so that the saw blade is separated from the die-cast part of the PCU middle cover. Control the motor to stop rotating, and complete the removal of the die-cast part of the PCU middle cover.

[0039] Furthermore, in the above-mentioned method for cutting off the die-cast material head of the PCU cover, step 6 specifically involves: controlling the motor to drive each saw blade to rotate, controlling the coolant nozzle to spray coolant onto the edge of the saw blade, and controlling the drive device to drive the slide to move towards the positioning seat, so that the saw blade contacts the flow channel component of the die-cast part of the PCU cover and cuts off the flow channel component, causing it to fall downwards.

[0040] Furthermore, in the above-mentioned cutting method of the die-casting material head cutting device for the PCU cover, step 6 specifically involves: controlling the motor to drive each saw blade to rotate, controlling the coolant nozzle to spray coolant onto the edge of the saw blade, and controlling the drive device to drive the slide to move towards the positioning seat, so that the saw blade contacts the flow channel component of the die-casting part of the PCU cover and cuts off the flow channel component, causing it to fall downwards. The movement of the drive device is a two-stage movement. The first stage of movement is the process of the saw blade moving from the initial position to a position close to the flow channel component, and the second stage of movement is the process of the saw blade moving from a position close to the flow channel component to a position where the flow channel component is completely cut off. The speed of the first stage of movement is higher than the speed of the second stage of movement.

[0041] The beneficial effects of this invention are as follows: By designing a specific structure and positional relationship, the invention utilizes the coordinated operation of various structures such as a positioning seat, crossbeam, first drive cylinder, clamping component, second drive cylinder, slag removal plate, first rotary cylinder, first clamping block, second rotary cylinder, second clamping block, support seat, guide rail, slide, drive device, and saw blade, along with a specific cutting processing method. This allows for the precise and automated removal of the slag and flow channel components of the die-cast PCU middle cover through two independent fixing and cutting processes. Compared to the prior art, where removing the slag head from the PCU middle cover requires manual hand-held electric saw cutting, this invention significantly improves work efficiency and ensures stable and uniform cutting quality during mass production of PCU middle covers.

[0052] Base 1;

[0053] Positioning seat 2, which is connected to base 1, is used to position the die-cast part 19 of the PCU middle cover;

[0054] Crossbeam 3, which is located above the positioning seat 2;

[0057] The second drive cylinder 6 has its cylinder body fixed vertically downward to the crossbeam 3, and the second drive cylinder 6 is located in front of the first drive cylinder 4.

[0058] The slag bag removal plate 7 is connected to the lower end of the piston rod of the second drive cylinder 6. The bending angle of the slag bag removal plate 7 is the same as the contour of the side where the slag bag 191 of the PCU cover is located.

[0062] The second clamping block 91 is connected to the piston rod of the second rotary cylinder 9;

[0063] Support 10, which is connected to base 1, is located in front of positioning seat 2, and there is a gap 11 between support 10 and positioning seat 2;

[0064] Guide rail 12, the guide rail 12 is connected to the upper part of the support base 10, and the guide rail 12 is arranged in the front-back direction;

[0065] Slide 13, which is slidably connected to guide rail 12;

[0066] Drive device 14, the drive device 14 is used to drive slide 13 to move along guide rail 12;

[0067] Saw blade 15, the saw blade 15 is rotatably connected to slide 13, and a plurality of saw blades 15 are arranged in a line along the left and right direction, and the axis of the saw blade 15 is vertical.

[0068] An electric motor is connected to the saw blade 15 for driving the saw blade 15 to rotate.

[0069] In the above structure, the first drive cylinder 4 and the second drive cylinder 6 can be hydraulic cylinders, pneumatic cylinders, electric cylinders or other drive mechanisms. As a preferred embodiment, the first drive cylinder 4 and the second drive cylinder 6 can be pneumatic cylinders.

[0070] The cutting method of the die-cast part 19 of the PCU cover described above includes the following steps:

[0071] Step 1: Position the die-cast part 19 of the PCU middle cover on the positioning seat 2, with the inner surface of the PCU middle cover facing upward, so that the slag pocket 191 of the die-cast part 19 of the PCU middle cover is located in the gap 11 between the positioning seat 2 and the support seat 10.

[0072] Step 2: Control the piston rod of the first drive cylinder 4 to move downward, driving the clamping part 5 to press the die-cast part 19 of the PCU middle cover from above; control the first rotary cylinder 8 to rotate counterclockwise, driving the first clamping block 81 to clamp the recessed part on the left side of the PCU middle cover; control the second rotary cylinder 9 to rotate counterclockwise, driving the second clamping block 82 to clamp the recessed part on the right side of the PCU middle cover.

[0073] Step 3: Control the piston rod of the second drive cylinder 6 to move downward, drive the slag bag cutting plate 7 to cut the slag bag 191 from top to bottom, and make the slag bag 191 fall out of the gap 11 between the positioning seat 2 and the support seat 10;

[0074] Step 4: Control the piston rod of the second drive cylinder 6 to move upward, which will drive the slag removal plate 7 to move upward and detach it from the die-cast part 19 of the PCU cover;

[0075] Step 5: Control the piston rod of the first drive cylinder 4 to move upward, driving the clamping part 5 to move upward and disengage from the die-cast part 19 of the PCU middle cover;

[0076] Step 6: Control the motor to drive each saw blade 15 to rotate, control the drive device 14 to drive the slide 13 to move towards the positioning seat 2, so that the saw blade 15 contacts the flow channel 192 of the die-cast part 19 of the PCU cover, and cuts off the flow channel 192, which then falls downwards.

[0077] Step 7: Control the drive device 14 to move the slide 13 away from the positioning seat 2, so that the saw blade 15 is separated from the die-cast part 19 of the PCU middle cover, control the motor to stop rotating, and complete the removal of the die-cast part 19 of the PCU middle cover.

[0078] After the removal is completed, the first rotary cylinder 8 is controlled to rotate clockwise, causing the first clamping block 81 to disengage from the recess on the left side of the PCU middle cover. The second rotary cylinder 9 is controlled to rotate clockwise, causing the second clamping block 82 to disengage from the recess on the right side of the PCU middle cover. The removed PCU middle cover is then removed manually or by a robotic arm, and the next PCU to be removed is placed on the positioning seat.

[0079] In the above embodiment 1, in order to automate the above cutting method, a PLC can be set up, and proximity switches can be set up at multiple locations of the cutting equipment. By electrically connecting the PLC to each proximity switch, the first drive cylinder 4, the second drive cylinder 6, the motor, the first rotary cylinder 8, and the second rotary cylinder 9 respectively, the next step can be triggered by the recognition of each proximity switch. Alternatively, the control sequence of the above components can be realized by pre-setting the corresponding program in the PLC.

[0080] Example 2

[0081] The die casting part 19 cutting device for PCU cover described in Example 1 further includes a cooling assembly, which includes a coolant storage tank and a coolant spray pipe connected to the storage tank. The end of the coolant spray pipe is provided with a coolant nozzle 16, which faces the edge of the saw blade 15.

[0082] In the above method, step 6 specifically involves: controlling the motor to drive each saw blade 15 to rotate, controlling the coolant nozzle 16 to spray coolant onto the edge of the saw blade 15, and controlling the drive device 14 to drive the slide block 13 to move towards the positioning seat 2, so that the saw blade 15 contacts the flow channel 192 of the die-cast part 19 of the PCU cover, and cuts off the flow channel 192, causing it to fall downwards.

[0083] Preferably, step 6 specifically involves: controlling the motor to drive each saw blade 15 to rotate, controlling the coolant nozzle 16 to spray coolant onto the edge of the saw blade 15, and controlling the drive device 14 to drive the slide 13 to move towards the positioning seat 2, so that the saw blade 15 contacts the flow channel 192 of the die-cast part 19 of the PCU cover and cuts off the flow channel 192, causing it to fall downwards. The movement of the drive device 14 is a two-stage movement. The first stage of movement is the process of the saw blade 15 moving from the initial position to a position close to the flow channel 192, and the second stage of movement is the process of the saw blade 15 moving from a position close to the flow channel 192 to a position where the flow channel 192 is completely cut off. The speed of the first stage of movement is higher than the speed of the second stage of movement.

[0084] In the above method, a corresponding program can be set by PLC, that is, when the saw blade 15 is about to approach or contact the cutting point of the die-cast part in the PCU, the valve set at the pneumatic coolant nozzle 16 sprays coolant onto the saw blade 15.

[0085] The optimization of Embodiment 2 above enables the saw blade to cut the flow channel 192 more smoothly, effectively reducing burrs at the cut.

[0086] Example 3

[0089] In the above embodiment 3, a conveyor belt can be installed below the gap between the positioning seat 1 and the support seat 10, and below the side of the positioning seat 1 away from the support seat 10, so that the cut slag bag 191 is conveyed to the collection box for collection from the conveyor belt below the gap between the positioning seat 1 and the support seat 10. The cut flow channel component 192 can be conveyed to the collection box from the side of the positioning seat 1 away from the support seat 10, which is convenient for recycling and recasting.

[0090] Example 4

[0091] The die-cast part 19 material head removal device for the PCU cover described in Example 1 further includes a mounting plate 17, which is connected to the lower end of the piston rod of the second drive cylinder 6. The slag bag removal plate 7 is fixed to the mounting plate 17. The mounting plate 17 is provided with two limiting shafts 18 parallel to the piston rod of the second drive cylinder 6. The two limiting shafts 18 are symmetrically distributed on both sides of the second drive cylinder 6. The crossbeam 3 is provided with bushings that slide with the limiting shafts 18.

[0092] The above structure can improve the stability and accuracy of slag bag 191 removal.

[0093] Example 5

[0094] The die casting part 19 of the PCU cover described in Example 1 is a material head removal device, wherein the clamping part 5 includes two cylindrical clamping blocks distributed on the left and right.

[0095] In the above structure, the clamping component 5 includes two cylindrical clamping blocks distributed on the left and right. The cylindrical clamping blocks cooperate with the PCU middle cover to limit the movement, so that the PCU middle cover can be clamped more stably on the positioning seat 2, and avoid loosening during cutting.

[0096] Example 6

[0097] The die casting part 19 of the PCU middle cover described in Example 1 is provided with a positioning post on the positioning seat 2 for passing through the through hole of the PCU middle cover.

[0098] In the above structure, by setting a positioning post on the positioning seat 2 for passing through the through hole of the PCU middle cover, the PCU middle cover can be clamped more stably on the positioning seat 2, avoiding loosening during cutting.

[0099] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention.
